Very funny answers. But imagine a young person maybe not too experienced with things smashing the tube and having glass fly up and hit them in the face or what if I am in a wheel chair or vision impaired?
I am just saying that is a really bad policy for a manufacturer to take not knowing anything about their customer. OSHA would be all over this here in the USA.
I sent them the photos of the tester and tube showing the internal short which should have been enough. But I think the point was missed that they would only send one replacement tube. Based on the deviation in specs I saw with their other products the chance it would be matched to the other tubes is very low.
I usually order more than what I need and then match them myself once I get them because they are almost never matched properly. But these were a little expensive to do that.
Business practice in China is to ship USA customers their shit tubes and keep the better ones for manufacturers and preferred customers. Just watch the recent video from Decware about tube supply.
